DETAILED DESCRIPTION

[0019] Reference Figures 1 to 3 The embodiments of the utility model are further described.

[0020] A feeding device of a die-cutting machine comprises a bottom plate 1, a first baffle plate 2, a second baffle plate 3, a support block 4, a conveying mechanism 5, a lifting mechanism 6 and a limit plate 12. The first baffle plate 2 and the second baffle plate 3 are respectively fixed at both ends of the bottom plate 1, the conveying mechanism 5 is fixed on the first baffle plate 2, the support block 4 is provided with two bottom ends respectively fixed on the bottom plate 1, the lifting mechanism 6 is placed on the bottom plate 1, and the two ends of the limit plate 12 are respectively fixedly connected to the first baffle plate 2 and the second baffle plate 3.

[0021] The lifting mechanism 6 includes a bearing plate 61, a fixing box 62, a gear 63, a first motor 64 and a rack 65. The bearing plate 61 is placed on the bottom plate 1. The fixing box 62 is fixed to the bottom end of the bottom plate 1. The bottom plate 1 is provided with a connecting groove 7 connected to the fixing box 62. The first motor 64 is fixed on the supporting block 4. The first motor 64 includes a first rotating shaft 8. The first rotating shaft 8 passes through the supporting block 4 and extends into the fixing box 62 to be rotatably connected to the fixing box 62. The gear 63 is placed in the fixing box 62 and is fixedly connected to the first rotating shaft 8. One end of the rack 65 is fixedly connected to the bearing plate 61. The other end of the rack 65 passes through the connecting groove 7 and extends into the fixing box 62 to mesh with the gear 63 for transmission.

[0022] By starting the first motor 64, the first motor 64 runs to drive the first rotating shaft 8 to rotate, and the first rotating shaft 8 drives the gear 63 to rotate. Since the gear 63 is meshed with the rack 65, the gear 63 drives the rack 65 to move vertically, and then the rack 65 drives the carrying plate 61 to move, and then the cardboard pile placed on the carrying plate 61 is lifted, until the cardboard at the top of the cardboard pile touches the transmission mechanism, and the cardboard touching the transmission mechanism is started to be transmitted to the die-cutting machine, thereby realizing automatic loading, and at the same time, the gear 63 continues to rotate, thereby driving the rack 65 to move, and then driving the carrying plate 61 to continue to rise, until the cardboard hits the transmission mechanism, thereby realizing the loading of the next cardboard, and the reciprocating process is followed to realize the effect of continuous loading.

[0023] The transmission mechanism 5 includes a second motor 51, a first sleeve 52 and a second sleeve 53. The second motor 51 is fixed on the first baffle 2. The second motor 51 includes a second rotating shaft 9. The second rotating shaft 9 passes through the first baffle 2 and the second baffle 3 in sequence and is rotatably connected to the first baffle 2 and the second baffle 3. The first sleeve 52 and the second sleeve 53 are respectively sleeved on the second rotating shaft 9 and are fixedly connected to the second rotating shaft 9. The first sleeve 52 and the second sleeve 53 are both sleeved with a rubber sleeve 11.

[0024] The second motor 51 drives the second shaft 9 to rotate, and then the second shaft 9 drives the first sleeve 52 and the second sleeve 53 to rotate, and then the first sleeve 52 and the second sleeve 53 drive the rubber sleeve 11 to rotate, and then the rubber sleeve 11 touches the cardboard to transmit the cardboard to the die-cutting machine in sequence. At the same time, the friction force of the rubber sleeve 11 can make the cardboard slide out of the cardboard pile more easily, thereby improving the work efficiency.

[0025] Corresponding guide blocks 10 are respectively provided on the inner walls of the first baffle plate 2 and the second baffle plate 3;

[0026] When the cardboard is conveyed to the die-cutting machine, the cardboard contacts the guide block 10, thereby playing a guiding role. At the same time, a limit plate 12 is provided so that the cooperation with the guide block 10 allows the cardboards to be conveyed to the die-cutting machine one by one during the conveying process.

[0027] Working principle: First, the first motor 64 is started to rotate the first shaft 8, and then the first shaft 8 drives the gear 63 to rotate, the gear 63 is meshed with the rack 65, and then the gear 63 rotates to drive the rack 65 to move vertically, and then the rack 65 drives the carrier plate 61 to move, and then the carrier plate 61 moves the accumulated cardboard upward until the cardboards accumulated on the top are in conflict with the guide block 10 and the rubber sleeve 11, and then the second motor 51 is started, and then the second shaft 9 is rotated, and then the second shaft 9 drives the first sleeve 52 and the second sleeve 53 to rotate, and the first sleeve 52 and the second sleeve 53 drive the rubber sleeve 11 to rotate, and the cardboard in conflict with the rubber sleeve 11 is transmitted to the die-cutting machine through the rotation of the rubber sleeve 11. When the cardboard placed on the top of the cardboard pile is sent to the die-cutting machine, the carrier plate 61 continues to rise until the next cardboard conflicts with the rubber sleeve 11 and the guide block 10, and the cardboard is sent to the die-cutting machine again through the rotation of the rubber sleeve 11, and it is repeated in sequence until all the cardboards placed on the carrier plate 61 are sent to the die-cutting machine.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
